I don't believe this has ever been done before.

lekh2003 said:There is some Russian borehole where they went deeper than this mission, but they didn't make it to the mantle:
Yeah, I understand. It was their mission to reach really deep, not the mantle.davenn said:yeah, because they were drilling through very thick continental crust rather than the much thinner oceanic crust planned for this new mission
Find the composition of the mantle with more accuracy.ElliotSmith said:What will they do after they break through to the mantle?
What is the purpose of this?
A lot can happen in 12 years.But they're hopeful they can begin drilling by 2030
Arman777 said:It reminded me a movie "The Core".
The Earth's mantle is the layer between the crust and the core of the Earth, and it makes up about 84% of the Earth's volume. Scientists want to drill into it because it holds vital information about the Earth's formation and composition, which can help us better understand the planet's history and evolution.
The Earth's mantle extends from about 6 miles (10 kilometers) below the ocean floor to about 1,800 miles (2,900 kilometers) deep. Scientists plan to drill as deep as possible, potentially reaching depths of 4,000 miles (6,400 kilometers) in the future.
Drilling into the Earth's mantle is an extremely difficult and complex task. The extreme heat and pressure at these depths can damage drilling equipment and make it difficult to retrieve samples. Additionally, the cost and logistics of such a project are significant challenges that need to be addressed.
Scientists hope to learn more about the Earth's composition, structure, and history by studying samples from the mantle. This can provide insights into the formation of the Earth and its geological processes, as well as information about the materials and resources that exist within the mantle.
Aside from advancing our understanding of the Earth, drilling into the mantle could also have practical benefits. It could provide access to valuable minerals and resources that are currently inaccessible, and it could also help us better predict and prepare for natural disasters, such as earthquakes and volcanic eruptions.
